Description
Technical Field
The present invention relates to the field of wireless technologies, and in particular, to an antenna adjustment method, a shipborne antenna system, a shipborne antenna device, and a network device.
Background
There is a need for a ship at mid-to-open sea to communicate with a shore base station, but because the distance of the ship from the base station is much greater than the distance between a land user and the base station, the signal quality of terminals on the ship is poor and is prone to dropped. For this purpose, signal transceiving equipment can be added on the ship, providing stronger transceiving capabilities than ordinary terminals, such as micro-amplification, CPE (Customer premises equipment, user terminal equipment) and the like. The existing signal receiving and transmitting equipment also supports the pull-out antenna, and can deploy the return antenna outside the cabin so as to avoid attenuation of the cabin body to signals. However, the pullout antenna is generally only an omni-directional antenna, due to the varying position of the vessel on the sea.
However, the omni-directional antenna has a relatively uniform signal receiving and transmitting capability in all directions, but also causes a problem of low antenna gain, so that when a ship is far away from a base station on shore, the ship still drops due to insufficient signal level, and the communicable distance between a terminal on the ship and the base station on shore is limited.

Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved more apparent, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
It should be appreciated that reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
In various embodiments of the present invention, it should be understood that the sequence numbers of the following processes do not mean the order of execution, and the order of execution of the processes should be determined by the functions and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.
In addition, the terms "system" and "network" are often used interchangeably herein.
In the examples provided herein, it should be understood that "B corresponding to a" means that B is associated with a from which B may be determined. It should also be understood that determining B from a does not mean determining B from a alone, but may also determine B from a and/or other information.
As shown in fig. 1, an antenna adjustment method according to an embodiment of the present invention includes:
at step 101, at least one candidate base station is determined.
It should be noted that, the location information (i.e., latitude and longitude information and altitude information related to the band antenna) of the relevant base station (i.e., the first base station) in the navigation area range may be downloaded and stored in advance according to the navigation area range of the ship, so that when the ship is navigated, it may be determined which base station may be used as the candidate base station according to the location of the ship and the location information of the first base station.
For example, according to the positional relationship between the ship and the base station, the base stations outside the line of sight of the target antenna may be excluded, the base stations may be sorted according to the distance from the ship, and then N base stations closer to the ship may be selected as candidate base stations according to the distance from the near to the far.
And 102, receiving signals sent by the at least one candidate base station by adjusting the beam direction of the target antenna.
In this step, the beam pointing direction of the target antenna may be controlled and adjusted so that the signal transmitted by the candidate base station is received after the beam pointing direction of the target antenna is adjusted.
And step 103, determining a target base station of the target antenna according to the signal strength of the signal, and taking the beam direction corresponding to the target base station as a target beam direction.
It should be noted that, the antenna adjustment method in this embodiment may be triggered by a set time interval (for example, the beam direction of the target antenna is adjusted according to the antenna adjustment method provided by the embodiment of the present invention every 1 hour) or other conditions during the sailing process of the ship, and then a suitable target base station is screened and determined according to the position of the ship, so as to implement the technical effect of automatically adjusting the direction of the target antenna and making it point to the target base station, so as to maintain the communication quality between the equipment on the ship and the shore base station.
According to the embodiment of the invention, the target antenna is adjusted to direct, so that a signal can be received from the candidate base stations, a proper target base station is determined according to the signal strength of the signal, and the beam direction corresponding to the target base station is used as the target beam direction, so that network service can be provided for the terminal on the ship where the target antenna is located through the target base station, the communication distance between the terminal on the ship and the shore base station is improved, and the user experience is improved.
Optionally, the target antenna comprises a directional antenna and/or an antenna array.
Here, the antenna array can adjust beam pointing by means of electrical tuning without mechanical rotation.
It should be noted that, in the prior art, an omni-directional antenna is generally adopted as the shipborne antenna, if the gain of the omni-directional antenna is to be improved, the oscillator of the antenna needs to be increased, which results in the antenna having too long length (for example, more than 3 meters), and thus, the installation and deployment of the antenna are difficult. The target antenna in the embodiment of the invention can be a directional antenna or an antenna array, and compared with the traditional shipborne omni-directional antenna scheme, the target antenna can realize higher antenna gain under smaller antenna size, thereby improving the receiving and transmitting capacity of the shipborne antenna system, and bringing convenience to installation because of the small antenna size.
In this embodiment, by utilizing the high gain characteristic of the directional antenna, the signal receiving and transmitting capability of the shipboard device can be improved without significantly increasing the antenna size, and the installation is convenient.
As an alternative embodiment of the present invention, step 101 may specifically include:
step 1011, acquiring first position information of the target antenna and second position information of at least one first base station.
It should be noted that, the first location information may be longitude and latitude coordinates of the target antenna, and the location of the target antenna may also be understood as the location of the ship where the target antenna is located. For example, a positioning device may be mounted on the ship, through which the current GPS (Global Positioning System ) location information of the ship (i.e., longitude and latitude coordinates of the ship) may be located.
Step 1012, determining at least one candidate base station according to the first location information and the second location information.
In this embodiment, the candidate base station may be selected from at least one first base station according to the position information of the target antenna and the position information of the first base station, and the range may be narrowed so that the target base station may be determined more quickly in the subsequent steps.
As an alternative embodiment of the present invention, step 1012 may specifically include:
determining the first base station meeting a first preset condition as the candidate base station according to the first position information and the second position information, wherein the first preset condition comprises at least one of the following:
condition (1): the first base station is in the sight distance range of the target antenna;
Condition (2): the distance between the first base station and the target antenna is smaller than or equal to a preset distance threshold;
condition (3): and when the first base stations and the target antennas are sequenced from near to far, the first base stations are arranged in the front N bits, and N is a positive integer.
It will be appreciated that some of the first base stations may be out of range of the target antenna due to the effects of earth curvature. In practical application, when screening candidate base stations, first base stations outside the line-of-sight range of the target antenna can be eliminated according to the condition (1), and then the candidate base stations are further screened out from the rest first base stations according to the condition (2) and/or the condition (3). For example, the distances (for example, L1, L2, L3.) between each first base station (for example, B1, B2, B3.) and the target antenna are calculated, and then the candidate base stations are sorted and screened according to the distances to form a base station list. For example: the base stations corresponding to the near-far marks are respectively: bx1, bx2,..bxn. In the process of screening to obtain candidate base stations, the screening conditions may be: the distance between the antenna and the target antenna is smaller than or equal to a preset distance threshold, and the distance between the antenna and the target antenna can also be: the first N base stations closest to the target antenna.
In this embodiment, a more suitable base station may be initially selected from the first base stations as a candidate base station according to the position of the ship (i.e., the first position information of the target antenna) and the second position information of the first base station, so as to narrow the range, so that the target base station can be determined more quickly through the subsequent steps.
Optionally, the second location information includes: coordinate information and altitude; wherein determining that the first base station is within the line of sight of the target antenna comprises: determining a ground surface distance between the target antenna and the first base station according to the first position information of the target antenna and the coordinate information of the first base station; determining an arc angle between the first base station and the target antenna according to the ground surface distance; determining a target reference altitude according to the radian angle; and determining that the first base station is in the sight range of the target antenna under the condition that the altitude of the first base station is greater than or equal to the target reference altitude.
For example, first, the ground surface distance (Lm) between the first base station and the target antenna is calculated, and assuming that the earth radius is R, the arc angle between the first base station and the target antenna is: lm/R, the altitude of the base station in the line-of-sight range of the target antenna should be not lower than: r (sec (Lm/R) -1), that is to say the target reference altitude is: r (sec (Lm/R) -1). Then, if the altitude of the first base station is less than R x (Lm/R) -1, the first base station can be considered to be out of line of sight of the target antenna.
Optionally, the receiving the signal sent by the at least one candidate base station by adjusting the beam direction of the target antenna includes:
controlling the beam of the target antenna to sequentially point to each candidate base station in a candidate base station list, and receiving signals sent by the candidate base stations until the candidate base stations pointed by the beam of the target antenna meet a second preset condition; the candidate base stations in the candidate base station list are sequentially arranged from near to far according to the distance from the target antenna; the second preset condition includes at least one of:
(1) The candidate base station is positioned at the last bit of the candidate base station list;
(2) And the signal strength of the signal received from the candidate base station is greater than or equal to a preset strength threshold.
Specifically, the distance between the target antenna and the candidate base stations in the peripheral line-of-sight range can be calculated based on the current position information (i.e., the first position information) of the target antenna, then the candidate base stations are sorted according to the distance from near to far to form a candidate base station list, and finally the target antenna is controlled to enable the main beam of the target antenna to sequentially point to each candidate base station according to the sequence on the candidate base station list. In the process, a signal sent by a candidate base station is required to be received, the signal intensity value of the signal is detected, the signal intensity value is compared with a preset intensity threshold, and a target base station is determined according to a comparison result.
The order of the candidate base stations in the candidate base station list is assumed to be: bx1, bx2,..bxn.
Taking a candidate base station to which a beam of a target antenna is currently directed as a Bx1 as an example, detecting the signal strength of a signal received from the candidate base station as the Bx1, and if the signal strength is greater than or equal to a preset strength threshold, determining the candidate base station Bx1 as the target base station, and ending adjustment; if the signal intensity of the signal received from the candidate base station is greater than or equal to the preset intensity threshold, or each candidate base station in the candidate base station list is traversed, and the adjustment is finished.
It should be noted that, if each candidate base station in the candidate base station list has been traversed, but no candidate base station whose signal strength of the received signal (i.e., the signal received from the candidate base station) is greater than or equal to the preset strength threshold is found, the candidate base station corresponding to the received signal with the highest signal strength may be selected from the base station list as the target base station.
As shown in fig. 2, as an alternative embodiment of the present invention, controlling the beam of the target antenna to point to the candidate base station may specifically include:
First location information of the target antenna and third location information of the candidate base station are acquired.
Here, the first position information of the target antenna may be obtained by a positioning device mounted on the ship, and the third position information of the candidate base station is obtained by pre-stored information (i.e., the position information of the relevant base station within the navigation area of the ship downloaded and stored in advance).
And secondly, determining a first included angle formed by a connecting line between the target antenna and the candidate base station and the north direction according to the first position information and the third position information.
Taking the positional relationship shown in fig. 2 as an example, a first angle formed by the candidate base station Bx1 and the north direction is Φ2.
And thirdly, determining a second included angle formed by the target antenna and the north direction according to a reference azimuth angle of the target antenna and a heading angle of a ship where the target antenna is located, wherein the reference azimuth angle is an angle formed between the installation direction of the target antenna and a first direction of the ship, and the first direction is a direction of a ship longitudinal axis towards a ship head.
Taking the positional relationship shown in fig. 2 as an example, the course angle of the ship is Φ1, the reference azimuth angle is Φ0, and the second included angle is Φ1+Φ0.
And fourth, determining a third included angle between the candidate base station and the installation direction of the target antenna according to the first included angle and the second included angle.
Taking the positional relationship shown in fig. 2 as an example, the third included angle is: phi 2+ phi 1+ phi 0.
After the target antenna is installed, the installation direction of the target antenna may be recorded, so that the installation direction of the target antenna may be used as a reference starting point for adjusting the target antenna. In this way, when adjusting the beam pointing direction of the target antenna, it may be determined how to adjust the beam pointing direction of the target antenna according to the third included angle between the candidate base station and the installation direction of the target antenna, so that the antenna points to the candidate base station.
It will be appreciated that the mounting direction of the target antenna may be set in a first direction of the vessel, which may facilitate determination of a third angle between the candidate base station and the mounting direction of the target antenna. Of course, the installation direction of the target antenna may also be directed in other directions, such as the case shown in fig. 2, where the reference azimuth angle of the target antenna (i.e. the angular relationship between the installation direction of the target antenna and the first direction of the vessel) needs to be measured and recorded. It should be noted that the angle of phi 0 is signed, for example, the installation direction of the target antenna forms an acute angle with the first direction of the ship (e.g., in the case of fig. 2), the angle of phi 0 is signed if the installation direction of the target antenna is clockwise of the bow (e.g., in the case of fig. 2), and the angle of phi 0 is signed if the installation direction of the target antenna is counterclockwise of the bow.
And fifthly, controlling the beam of the target antenna to point to the candidate base station according to the third included angle.

That is, the candidate base station whose signal strength is greater than or equal to the preset strength threshold may be preferentially selected as the target base station, and if the candidate base station satisfying the condition cannot be found, one candidate base station having the highest signal strength may be selected from the candidate base station list as the target base station.
